To all whom it may concern:

Be it known that I, FLEMING H. `WEAVER,

a citizen of the United States, residing at Grii'lin, in the county ofSpalding and State of Georgia, have invented a new and usefulCultivating Implement; and l do hereby declare the following to be afull, clear, and exact description of the invention, such as `willenable others skilled inthe art to which it appertains to make and usethe same.

This invention relates to implements for cultivating the soil, and ithas particular reference to that class of cultivators in which thecultivator teeth are pivotally connected with and carried bypairs ofbars disposed in parallel relation, said pairs of bars being pivotallyconnected with a beam or draft-bar, under which construction'` theparallel bars are capable ofadjustment to dierent positions, thuseiiecting a corresponding adjustment of the cultivator teeth, which'latter may be arranged in V-shape with the apex of the V point in aforward or rearward direc tion, as may be desired; the said teeth may bedisposed in a straight row at approxii mately right angles to the beam;or they may be disposed in a diagonal row with. relation to the beam.`Again, by proper adjustment of the parallel bars, the cultivator teethmay be spaced various distances apart so as to make furrows more. orless closely together, as may be desired. Y p

The present invention has for its object to simplify and improve the,construction and operation of this class of cultivators; and

with these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arran ement and combination of partswhichrwill c e hereinafter fully described and particularly pointed outin the claims. A

In the accompanying drawings has been illustrated a simple and preferredform" of the invention; it being, however, understood be resortedto whendesired.

In the drawings-Figure 1 is a top plan view of a cultivator constructedin accordance with the invention. Fig. 2 is afbettom plan view showing adifferent arrangement of the teeth. Fig. 3 isa side elevation partly insection. Fig. 4 is a perspective despecifictioii of Letters Patent.

tail view of clamp constituting the adjusting and fastening member. Fig.5 is a sectional detail view of said clamp.

Correspondin parts in the several figures are denoted by ike charactersof reference. y The beam 5, which is in the nature of an ordinary plowbeam, is provided with handles 6, bymeans ofwhich it may be manipulated.Upon the under side of the beam there are pivoted two pairs of bars 7,7, and 8, 8, extending in opposite directions from the beam.y The pinsor bolts 9 with which these bars are pivoted, extend vertically throughthe beam, which latter is provided upon its upper side with a wear-plate10.

The cultivator teeth T are constructed, each of a single strap of steelor other metal, bent to form a shank 11, provided at its lowerV end withan earth engaging point 12,

`,and having at its upper end a return bend 13connecting the upper sidesof two of the bars 7, 7, and 8, 8, with which the return bends of 'theteeth are connected pivotall by means of pins or rivets 14. Thus it wi lbe seen that each pair of parallel bars carries a set of teeth, one suchset of teeth being disposed at each side of the beam 5. It will also beseen that by moving the parallel bars upon the pins or bolts 9, wherebythey are pivotally connected. with the beam, the outer or free ends ofsaid parallel bars may bemoved in a forwardly or rearwardly direction,as may be desired; the sets of teeth may thus be adjusted in V-shapedrelation with the apex of theV `J-point in a forward or in a rearwarddirection, as may be desired; or the parallel bars may be disposed inlongitudinal alin'ement upon opposite sides of the beam, either atright-angles to the latter or at various deviations from a right angle.The cultivator may thus be used for right and lefthand work, as may bedesired, or

for hilling or ridging the ground, the dirt being thrown towards thecenter or in an outward direction, as may be desired. Thus theimprovedcultivator may be used for a great variety of purposes by a very sim leand easily accomplished adjustment of t Y e teeth. Moreover, it will beseen that by proper. adjustment of the parallel bars the distancebetween the individual teeth may be varied, said teeth being placed moreor ess closely together so as to make the furrows at any desireddistance apart. Under the lconstruction described, the teeth constitute`spring teeth which will do very efficient work; the teeth, it will beobserved, are connected with the parallel bars by the return bends only,andthe shanks of the teeth will not be weakened by forming bolt holes orapertures therein, nor will the efficiency of the spring shanks bedecreased bythe presence of such holes or apertures. The outerextremities of the front bars 7 and 8, are connected with one of thebolts 9, by means of braces 16, which serve to increase the strength andstability of the device.

Upon the beam 5, adjacent to the rear end of the latter, there ispivotally mounted a standard 17, which may be appropriately constructedof a single strap of metal bent to form the elongated U-shaped standardwhich is pivoted upon the beam by single transverse bolt 18. Thisstandard carries a bulltongue 19, of ordinary construction, whichconstitutes a central tooth of the improved implement, which it isfrequently desired to use for the purpose of avoiding an excessive gapbetween the two middle teeth T of the device.

Suitably secured upon the beam 5, is a clip-plate 20, having downwardlyextending pin 21, which is screw-threaded as shown and provided with awing-nut 22. A brace 23 which is pivotally connected with the standard17 is provided near its free end with a slot 24, adapted to engage thepin 21. Pivotally connected with the outer extremity of the rear of theparallel bars 7 and 8, are arcuate brace-bars 25, each provided with aseries of apertures 26, adapted forengagement with the pin 21. By meansof these arcuate brace-bars the pairs ofparallel bars carrying sets ofcultivator teeth may be retained in position at various adjustments, thebrace bars 23 supporting the standard 17, being likewise retained, andthe several braces being firmly secured by means of the single wing-nut22. By this simple construction it will be seen that any desiredadjustment may be effected quickly and in a very thorough and eflicientmanner. lt will furthermore be seen that when desired the brace 23 maybe detached from the pin 21., thus permitting the standard 17 carryingthe bull-tongue 19 to be swung to an inoperative position in the rear ofthe beam where it may be supported in any suitable and eilicient manner.

From the foregoing description taken in connection with the drawinghereto annexed,

the operation and advantages of this invention will be readilyunderstood by those skilled in the art to which it appertains. Theconstruction is simple and inexpensive, and it will be found thoroughlyeilicient for the purposes for which it is provided.

Having thus described the invention, what is claimed is:

In a cultivating implement, a beam, oppositely extending pairs ofparallel bars pivoted upon the underside of the beam, eultivator teethhavin0V return bends pivoted upon the pairs of parallel bars, arcuatebraces pivoted upon the under sides of the rear paral lol bars adjacentto the outer extremities of said bars, said braces being provided withapertures formed at intervals therein, a clip plate secured upon thebeam and having a downward extending screw-threaded pin adapted to beengaged by the arcuate brace bars, and a wing nut upon thescrew-threaded pin.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FLEMING H. WEAVER.
